If the line segment bisector divided Andy's original line segment into two equal pieces that are each 2.9 centimeters long, we can find the total length of the original line segment by adding the lengths of the two pieces together.
Since each piece is 2.9 cm long, the original length of the line segment is:
\[ 2.9 , \text{cm} + 2.9 , \text{cm} = 5.8 , \text{cm} \]
Therefore, the correct answer is 5.8 cm.
The reasoning is based on the definition of a line segment bisector: it divides the line segment into two equal halves. Since each half is given as 2.9 cm, the total length must be twice that amount.
